When did ocean sailors realise that the shortest path on the globe is a great-circle? I would suggest that any sailor looking at a globe would understand geodesics pretty quickly. But there are other contributions to a successful voyage beyond distance: safety, supplies, etc. The Phoenecians are known to have traveled within sight of shore, for example: en.wikipedia.org/wiki/File:PhoenicianTrade.png |

What evidence of the big bang theory does exist? I'm certainly not qualified as a physicist, but I did want to add to the mix that what we call the big bang singularity isn't the only solution to the relativity equations. Stephen Hawking in particular rejects the necessity of a singularity - see en.wikipedia.org/wiki/Hartle%E2%80%93Hawking_state |

Who first made the connection between the Mayan calendar and something bad happening in 2012? My first exposure to "the end is coming on December 22, 2012" was in the final episodes of "The X Files." en.wikipedia.org/wiki/The_Truth_(The_X-Files) |

Can you only trace a phone call if they don't hang up? Thanks. Borror0 - I put the links back in. Luke, one other thing - there were devices (essentially small, portable AMA systems) called "traps" which could be connected to a line to record details about incoming calls. These were mainly used to catch nuisance callers, and could be installed after a subscriber filed a complaint. Then there are wiretaps, which actually record the call itself. |
